Wolves in Switzerland
Schnidrig said individual male wolves had moved over the border from France and Italy in the past decade and estimated there were now at least 11 wolves living in Switzerland and possibly another six. The animals reached the north side of the Alps three years ago and formed their first pack two years ago.
A Swiss student and a well-known wolf expert have joined forces to start developing a device that can monitor a sheep’s pulse and then release a powerful repellent to scare off a predator in the event of an attack. When the pulse gets too high, the collar will then activate a system to scare away the predator – high-frequency ultrasound waves that the wolf can hear but not the sheep, bright flashing lights or a blast of bear repellent pepper spray.
